GT-VTRAIN: Basic Training – North America

*** This course has been cancelled. Please contact GTI if you wanted to attend this class, so we can try to make alternate arrangements.***

This course is designed for new users of GT-VTRAIN and GT-SUITE. It will focus on the simulation of engine valvetrains through the use of VTDesign and GT-VTRAIN. The following topics will be covered:

   •Introductory concepts of GT-SUITE
   • Polynomial cam design
   • Valvetrain mechanism kinematics, quasi-static and dynamic modeling of valvetrains
   • Multi-body and torsional vibration modeling of camshafts and valvetrain systems
   • Post-processing (GT-POST)

The course will include hands-on use of VTDesign and GT-VTRAIN to construct models. It will enable participants to learn the basics and ask questions, while performing the following exercises:

   • Construction of a cam profile and a mechanical model of a valve branch in VTDesign
   • Kinematic and quasi-static analysis of a valve branch mechanism using VTDesign
   • Creating a dynamic (GT-VTRAIN) model of a valve branch
      o Automatically, by automatically exporting data from VTDesign
      o Manually, using basic pre-processor facilities in the standard GT-SUITE user interface
   • Multi-body dynamic analysis of a valve branch in GT-VTRAIN
   • Parameter sweeps, post-processing and frequency-domain analysis of results
   • Creating a model of a complete, multi-branch valvetrain and torsional/torsional+bending vibrations of camshaft

Part of the afternoon will be left open to discuss extra and more specialized topics. The topics will selected by the participants. Some possible topics are:

   • Hydraulic lash adjusters
   • Gear and chain drives
   • Combined valvetrain-cranktrain (GT-VTRAIN/GT-CRANK) models in GT-SUITE/mech
   • Transient simulations, optimization, links to MATLAB/Simulink, user-supplied models

Please let us know in advance if you want us to cover any of these or other topics.

Course will start at 9:00 AM and end at 5:00 PM
